View the state of input and output contacts
Path: Main > Configure Unit > Discrete I/O
Each cooling unit supports a user-defined input contact and a user-defined output contact. Each contact
monitors a sensor and responds to changes in the state of the sensor (open or closed).
Input State. Indicates the actual state of the input contact (Open or Closed). A cooling unit is On when
the state is normal and in Standby when the state is not normal.
Output State. Indicates the actual state of the output contact (Open or Closed). An alarm will cause the
output contact to change from the normal state.
Edit the normal state of input and output contacts
Path: Main > Configure Unit > Discrete I/O > Normal State
Configure the input contacts to cause alarm conditions based on the user-defined normal state. Output
contacts can map internal alarms and events to outside devices.
Input Norm. Set the normal state of the contact (Open or Closed). The cooling unit changes its
operating mode to Closed when the actual state differs from the normal state.
Output Norm. Set the normal state of the contact (Open or Closed). If the state of an alarm or event
mapped to this contact changes from the normal state, the contact also changes state.
Outpt Src. Define the type of output source (alarm), either Any Alrm or Critical, that causes the output
to change from its normal state.
